LIFE-BOAT.

'EECIFICATION forming part of Letters Patent N 0. 701,128, dated May 27, 1902.

Application filed June 4, 1901, Serial No. 63,164. (No model.)

, To all wtont tutt/.y concern.'

Be it known that I, AUGUST BAUMGART, a citizen of the United States, residing at Cornlea, Platte county, Nebraska, have invented a Life-Saving Boat, of which the following is a specification.

This invention relates to an improvement in life-saving boats.

The object of my invention is to provide a life-boat so constructed that the wash and force of waves shall be compensated in striking mylife-boat, so that the force ofthe waves and water will expend its force upon an outer movable covering to protect the life boat proper.

In the accompanying drawings lV haveshown in Figure 1 a central sectional view of a life-boat embodying my invention with portions broken away, while Fig. 2 shows a top View of a broken portion of my life-boat, disclosing the steering mechanism, while Fig. 3 discloses a broken detailrof the propeller.

My invention embodies a life-boat comprising a main approximately cylindrical chamber A, a forward bow-chamber B, and a rear or shallow chamber C. These three chambers are connected, the first and second by means of the narrow communication in the form of a collar ct, and the small circular annular section l) providing a communication between the chambers A and C. These-communications a and b are in the form of 'collars or cylinders and may form an integral portion or be secured to the chambers, which'they connect by any suitable means. The forward chamber B is provided above and u pon the top with a suitable door 2, secured by means of a hinge 3, and may be provided with a cleat 4 to form a water-tight union. Below the door is closed by means of a suitable latch. Entering the forward chamber B is a tube 6 to provide fresh air, which isv closed by means of a suitable valve 7, operated from below by a handle S. Upon the outside this tube 6 is further provided with a lid so, adapted' to be raised by the wash of the water should it rise that high to close this fresh-air communication 6. The rear chamber C is provided with one of these fresh-airA tubes 9, Within which is held a valve 10, provided with the operating-handle 11, as shown. This rear chamber C may be entered through a suitable door 50, held by the hinge 13, closed by the latch l2. This rear freshair pipe 9 is also provided with one of the lids x, provided with a round top.

Held within a suitable frame D Within the main chamber A is a shaft 14, operated by the crank 15, and this shaft supports acroWn-gear 16, which crown-gear meshes with a pinion 2l, secured to the shaft 17, which shaft works at its forward end within the standard 18 and within the bearing 19 within the chamber C. This shaft 17 is provided with a large gear 27, meshing with a small gear 28, secured to the shaft 29, to which shaft is secured a suitable propeller, and which shaft is held within the bearings 30 and 3,1.

Secured to the rear chamber C is a vertical shaft' 32, provided with an extension 33, to which extension is secured the connecting-rod 3S,which rod is in turn secured to the lever 39, pivoted by means of a pin 40, as shown. This lever 39 is provided with a suitable keeper 4l, adapted to work into the sector 42, so that the rudder 36, which is secured to the shaft 32, may be locked in any suitable position. This rudder 36 is held upon a pivot 35, which pivot passes through the bracket 34, secured to the shaft 32. The rudder 36 may be held in a horizontal or an upright position in being locked -by'means of a spring-ear 37.

The forward chamber B and the rear chamber Care each provided with a projecting ring 23,havingan outwardly-extendingflange 24, as shown. Revolubly working and upon the cylindrical collar-sections Ct and b are the disks H and K, which are provided with the stuffing-boxes 43 and 43', so as to insure a water-tight connection between the portions o and b. Connecting these disks H and K is an approximately barrel-shaped housing F, which is provided with a door 52, held by the hinge 53 and the keeper 54. This housingF forms an exterior' air-chamber Surrounding theinterior chamber. mitted to revolve freely with the wash of the water or the movement of the Waves, so that the shock of the waves is expended upon the housing F, which revolves in obedience to the Wave-power. To prevent longitudinal movement of the housing F are provided the rings 23 23 and the hooks 26, which Work over the flanges 24 of the rings 23. This buoyant airchamber F is provided below with a plurality This chamber F is per IOO of bearings 45, 47', and 49, supporting the collars 46, 48, and 50', upon which rest the interior chamber A.

Suitable ladders may be provided upon the exterior, as may also life-lines and light to oier a means of saving such as might come within grasp of the life-line.

The rear chamber C is provided with a suitable Window c, at which the pilot places himself.

This boat may be made of any suitable length and height, though it is thought that the chamber H should be made of such a height that a tall man could conveniently stand upright in the same.

To enter the chamber A, the passenger would of course have to crawl through the cylindrical chambers a and b, which form the bearings upon which the outer housing F revolves.

While the propeller-shafts are shown as beinnr adapted to be yoperated by manual power, it is of course understood that a gasolene-engine or any other suitable motor-power could be employed.

I do not wish to conne myself to any specified shape as regards the chambers A, B, C, or F, as the design of these chambers may be varied Without departing from the spirit of my invention.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

The combination in a boat of the character described of a main central chamber, a forward chamber, a narrow cylindrical communication between said forward and said main chambers, a rear chamber, a narrow cylindrical communication between said rear and said main chambers, a housing surroundingsaid main chamber providedwith end disks working upon said cylindrical communication to form an air-chamber surroundingl said main chamber, said housing and said disks being revolubly supported and held as and for the purpose set forth.
